Similar Figures in MathFigures that have the same shape… but are NOT the same size.
Do you see the similar figures in the photographs?
Why Learn About Similar Figures? Similar figures can be applied to solve real world problems.
For example, similar triangles can be used to find the height of a structure, the width of a river, the height of a tree etc.

Similar Figures
The corresponding angles have
equal measurements.
Use proportions to solve problems involving similar figures.
Definition: Figures that have the same shape BUT are not the same size.
The corresponding sides form a
proportion.
